I am planning a trip my first trip to Europe this late November. I have a little under 3 weeks' vacation time and need help. I will be traveling solo if that helps (32M). I absolutely want to visit Paris and Rome. However, I am stuck on the third place. I am planning on staying in each city 5 days and have allotted one day of travel between each (flights). Interested in everything travel; Museums, historical sights, food, night life, etc.
I am torn between the following locations: Berlin, Vienna, Prague, Barcelona, Athens.
"Is there someplace I missed and should look at?"
Help please!
